This paper reviews various functional materials used in desalination. Desalination of the abundant seawater resource has emerged as a promising technology to meet the current fresh water demands. For improved performance, often functional materials such as photocatalysts, electrocatalysts, photothermal materials, sorbents, antibacterial materials and magnetic materials are utilized in thermal, membranebased and other desalination technologies. With an aim to provide an insight on the existing research on functional materials and the purpose behind using such in desalination, this review collates different research studies of various functional properties and the subsequent materials utilized for those properties. New generation materials such as carbon nanotubes (CNTs) and graphene form a major part, where they exhibit multiple functionalities with improved water transport properties, and thus have been deemed as very attractive enhancers to the desalination technology. Nevertheless, most of the functional materials, such as nano-TiO2, nano-zeolites, graphene, CNTs and magnetic nanoparticles suffer from several limitations such as specialized synthesis techniques, agglomeration, leaching and environmental and health concerns. This review focuses on such challenges and suggests improvements for enhanced incorporation of these in the desalination technology. Lastly, emerging new technologies, advanced fabrication methods and novel functional hybrid materials are reviewed to equip the readers with the latest research trends. Thus, a comprehensive review is essential which will provide current and future researchers an insight on the importance and significance of utilizing functional materials in various desalination technologies.

“…A porous membrane's only advantage is its low internal resistance 181 . Moruno et al 8,182 have shown that ionizing commercially available polymers produce thinner and more conductive AEMs and CEMs that can improve the desalination rate and power output for MDC compared to baseline studies utilizing thick CEMs and AEMs with low ionic conductivity. To increase current density and power, the membrane's internal resistance must be as low as possible.…”

Increasing populations and urbanization put a lot of pressure on freshwater supplies and use. The increased demand for drinking water can be met by using seawater as a source of freshwater. Desalination and wastewater treatment have been energy-and time-consuming processes in recent years. Microbial desalination cells (MDCs) have gained considerable attention as an emerging technology because of their ability to treat wastewater, desalinate seawater, and produce electricity and value-added products. The efficiency and performance of this technology are affected by numerous factors. In this study, the effect of membranes on the efficiency and performance of this technology is examined. Anionic and cationic, carbon nanotube (CNT), bipolar and osmotic membranes were investigated. Anionic and cationic membranes, as well as their modifications, significantly influence microbial desalination cells.CNT-based membranes have shown significant improvements in water permeability, desalination capacity, strength, anti-fouling, and energy efficiency compared to other membranes. Bipolar membranes prevent the pH of the anode chamber from decreasing, which is essential for MDC operation. The use of FO membranes in microbial desalination cells still faces challenges; for instance, fouling is more likely in FO membranes than ion-exchange membranes, resulting in higher internal resistance and decreased water flux. MDC technology will require research into membrane fouling, electron transfer kinetics, material feasibility, microbial growth, and catalyst durability to be scaled and sustainable. As part of the feasibility study, the performance and stability of the reactor must also be examined.

Electrodeionization for the Bio-Succinic Acid Production Process

The production of succinic acid is of great importance due to the growing use of this compound in the industry. Biotechnological conversion requires the separation and purification of the main product. In the case of carboxylic acids, an additional problem is the alkaline environment of the subculture of microorganisms and, consequently, the need to convert the carboxylate formed into the free acid form of the product. Methods such as extraction or esterification do not separate the carboxylate. Acidification of fermentation broths with inorganic acids generates large fractions of waste. This is not only inconsistent with the principles of sustainable technology but also increases the cost of the process. Succinate conversion is possible through ion exchange or electrodialysis. However, these methods have limitations and drawbacks that reduce the efficiency of the process. A potential solution to these limitations is the application of applying electrodeionization (EDI) as a downstream stage in the technology of the bioproduction of carboxylic acids. Aqueous solutions of disodium succinate (pH 6.8) were converted into the electrodeionization module. In the final product of succinic acid, the residual sodium was determined at a level of 4% (conversion efficiency 96%). This paper presents preliminary research showing the possibility of applying electrodeionization of sodium succinate on an EDI module consisting of cation-exchange membranes and an ion-exchange resin. The results obtained are the basis for further research on this issue.
